  • Patent number: 8704800
    Abstract: A photo element includes a capacitor, a switch thin film transistor (TFT), a charge thin film transistor, and a photo thin film transistor. A voltage is charged to the capacitor through the charge TFT, and the output voltage of the capacitor is read through the readout line. The photo-induced current will affect the output voltage of the capacitor; therefore it is employed to determine whether the photo element is touched. Later, a reverse-biased voltage is applied to the photo TFT, such that the threshold voltage and sensitivity of the photo TFT can be maintained.
